This could result from the calcium chloride used. In such case, to maintain stability in the pH level of the water and prevent corrosion, it is advisable to add Potassium permanganate . Also one of the factors that can increase corrosion in such a scenario is the fact that conductivity of water in the tank increases due to the absorption of CO2 present in the air.

FAQ – Tiger Calcium
Calcium chloride increases the effectiveness of salt, therefore reducing the nuer of appliions necessary during storms and the cost of labour, equipment and materials. Calcium chloride also freeze-proofs abrasives to help them eed in ice and snow, which means that less material is lost to spreader bounce and stering by vehicle traffic.
